With a commitment to a 10-year lifespan and over 5000 deep cycles, it also offers 24-hour rapid-response technical support and online customer service, ready to assist you with any product-related issues at any time.
- 【10+ Year Lifespan】This 300ah lifepo4 battery is equipped with high-energy-density Grade A cells for extended runtime. It delivers over 4000 charge cycles (up to 10000+ cycles) and a service life exceeding 10 years—far surpassing lead-acid batteries (200-500 cycles/3-year lifespan) while providing 2000-3000 more cycles than comparable LiFePO4 batteries. Performance is continuously upgraded!
- 【Upgraded 200A intelligent BMS】Our 12V 300Ah LiFePO4 battery with integrated 200A Smart BMS delivers rock-solid power. Features bulletproof protection against overcharge, over-discharge, overcurrent, and short circuits. Its precision 0°C (32°F) low-temperature cutoff prevents damaging lithium plating in freezing conditions. With massive 300Ah capacity and intelligent safeguards, enjoy every appliance worry-free and unleash your adventure.
- 【4S4P Flexible Expansion】Compact and powerful, this LiFePO4 battery weighs just a mere 1/3 of comparable lead-acid batteries! Each 12V 300Ah lithium battery adopts a standardized design, supporting a 4S4P parallel connection expansion method. This means you can start with a single battery and gradually add more according to your actual needs, effortlessly building up to a 48V / 1200Ah large-capacity energy storage system. This solution is exceptionally well-suited for solar farms / industrial mobile power stations, enabling your RV, marine vessel, camper, or off-grid cabin to scale seamlessly alongside growing energy demands.
- 【All-Weather Safety Protection】 Built-in intelligent low-temperature protection automatically pauses discharge below -4°F and resumes charging above 32°F, ensuring reliable startups on icy mornings or hot summer afternoons. Seven layers of intelligent safeguards: BMS rigorously defends against overcharging, over-discharging, overcurrent, short circuits, and high temperatures.
